5.3.6.1 Sample modes explanation
-
Cumulative and differential:
The recorded numbers of particles are added up per channel (cumulative); starting with the
largest channel
In differential mode there are the absolute particle numbers per channel
Example:
Channel [µm]
Cumulative particle number
[PC]
Differential particle number [PD]
Calculation
0.3
1630
1000
= [PC,630]+[PD,1000]=[PK,1630]
0.5
630
350
= [PC,280]+[PD,350]=[PK,630]

= [PC,80]+[PD,200]=[PK,280]

= [PC,30]+[PD,50]=[PK,80]

Concentration:
Here, you can find the average numbers of the respective particles per channel; also called
particle density.
